Luxemburg border is a deposit high in silica and carrying 40 per cent, of iron, so that, by mixing, a self-fluxing burden can be obtained, and the usual furnace burden throughout the district runs 31 per cent, in iron and gives 2 per cent, of phosphorus in the pig-iron.
Table XXIV-D shows the composition of different grades of ore. The map shown in Fig. XXIV-B was originally made by Dr. Wedding, but was extended by Kirchhoff. The formation is made up of many different beds, and these vary in thickness, the deposit in the north being 180 feet thick, while in the south it is only 20 feet; but there is no regularity at intermediate points, either in thickness or in the arrangement of inter stratified rocks, and there is much faulting, in some cases the throw being 200 feet. As we go southwest into France the beds go down into the ground, get less in thickness and higher in silica. In Luxemburg the mines are owned partly by companies that acquired ownership many years ago, partly by railroads, built to get subsidies in ore lands, partly by farmers and private individuals, while part is controlled by the government. Much of the ore in Luxemburg is sold in the open market, while in Lothringen nearly all the property is in the hands of iron producers, and the great steel works in both Belgium and "Westphalia have acquired title to mineral lands. The ore supply in Luxemburg is good for one hundred years, at the present rate of consumption, but in Lothringen for eight hundred years. The mineral domain of this latter province covers one hundred thousand acres, half of which is owned by local steel companies. A good part of the remainder is owned by the companies operating steel works in Westphalia. Kirchhoff mentions the following as having mines in Lothringen and works in the Ehenish district:
Aachener Hiitten Act. Verein, GutehofCnungshiitte, Friederich Wilhelmslratte, Phoenix, Union, Horde, Hoesch, Eheinische and Krupp. In the Saar district we have G-ebriider Stumm, Eochlings, Burbach and Dillengen. Belgium is represented by the Angleur Company and by Cockerills. This list omits the local steel companies of Lothringen, all of which have their own properties.
Considerable ore is sold in the open market in Luxemburg, but little in Lothringen, so that the selling price in the former province will be a better measure of the market. Figures given by Dutreux show that from 1895 to 1899 the average market price varied from
